SHUT-Orr non Application leduly l2,

ing the necessity of the repairer making trips to other parts of a building in order to operate the usual shut-o valves. A further object is to provide the cold and hot water arms ofthe faucet with separate shut-ofi means, whereby the flow of the water from said arms may be suitably proportioned or equalized, in cases where the pressure of the cold and hot water is normally unequal, the shut-off mechanism consisting. of similar valves or gages, which are located in the cold and hot water arms of the fitting, and are arranged to be adjusted and set at will, for stopping, equalizing, or varying the volume of the water supply to the opposite sides of the dispensing valve without interference with the normal operation of the faucet.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing, in which- Figure 1 is a top plan view of sink or bath faucet to which my improvement is applied. Fig. 2 is a front side elevation'and partial central vertical section, the latter being taken on line 2 2 of Fig. 1; showing the individual shut-off Amechanisms in relation to the mixing valve. Fig. 8 is an enlarged side view of one of the shut-o valves. And Fig. 4 is respectively an end and a side elevation of one of the bushings that support the shut-off valves.

In the drawing, 2 designates the upright wall of a sink or bath tub, which usually supports the water dispensing iittings. 3 represents the upright cylindrical body of one type of the mixing valve, which is formed with a tapered seat 3', to receive the rotary valve 4, the latter being operable by a stem, whose top end is fitted with a handle 2a. The valve 4 is arranged to dispense water at different temperatures by the simple manipulation of the handle 2a, as shown by the SNK FAUCETS.

full and dotted lines in Figs. 1 and 2, wherein the full lines in Fig. 1 indicate that the valve 4 is positioned for dispensing' cold water, while the full lines in Fig. 2 indicate the positioning of the valve for dispensing warm water, which may comprise substantially equal volumes of hot and cold water. The dotted positions at the right in Figs. 1 and 2 indicate the drawing of hot water only.

ln Figs. 1 and 2, the bo-dy 3 is shown formed at its opposite sides with similar axially aligning circular recesses or sockets 3-3b, which are preferably threaded for the attachment of similar hollow water supply arms, as whose corresponding ends are externally threaded for screwing into said sockets. dered for preventing leakage. The remote ends of the arms 5 5 are preferably globular, and are formed with integral tubular arms 5, which together iith nipples 5" form the usual tail-pieces that extend rearyardly, pass through the wall 2, and connect respectively with the cold and hot water supply-pipes (not shown). Thel arms 5--5 conduct the cold and hot water respectively to the sockets ESL-3, from which the water flows through reduced aligning ducts 3C towards the valve chamber 3', and when the valve 4 is in the position shown in Fig. 2, the cold and hot water iiow simultaneous- 4ly through registering ports 4b-4", andthence into a common mixing chamber 4d, from which the mixture gravitates towards a common spout A, which may be either rigid or swingable. The passages 3C, at their outer extremities, V are preferably countersunk, as at 8d.

The shut-off means consist of similar hori- Zontally disposed valves, which may comprise plain brass or other rods, as 6-6, that are preferably disposed axially in the arms 5 5, their inner ends 6a, being beveled, and adapted to be seated in the mouths 3d of the 'j assages 3, for shuttingof entirely the supply of water to the valve 4. The outer' ends of the valves 6*(3, are correspondinglj7 threaded.l as at and are also provided with screwiriver slots G, by which the said valves are rendered adjustable axially in internally threaded bushings 7. The bushings 7 are also externally threaded and are screwed into threaded sockets 5d of the arms These joints are usually solomo The bushings 7, according to the present showing, are the sole supports for the shut-oit' valves 6--6. rihe sockets 5d are formed in correspondingly thickened portion 5C, which maybe cast in the globular extremities et the arnis 5-5. By comparing,` the rela e positions o't'- the valves 6-6 in Fig. 2 it Will be seen that the valve G is disposed closer to its seat 3d, than the valve 6', which indicates that because the cold writer is being' supplied at higher pressure Yhen is the hot Water, the opening controlled by the valve o niust he more constrictcd than is that ronnxolled bf' the valve 6 in order to allow eqn wie .es of hot and cold Water to tioiv towards the mixing valve el. By this construction and arrangement ot the valves 6 and 6 and the main valve e, either the het or the celd water supply may be readily and quickly regulated, and a relatively line adjustn'ient oil the parts inay be eiiected, by siniply adjusting the valves 6-6 ax*- ially, as shown and described, and when these valves are once adjusted they need not be disturbed, ntil the pres-sare of either the hot or the told Water supply is inc jeased or decreased. The bushings are preterably counterbored, as at 7, .for facilitating' applying` a suitable packing` 8, which prevents leakage through the sockets 5d. Because ot' the provision oi? the screw-driver slots instead et' handles, for adjusting` the shut-olf valves 6-6, the. adjustment ot the said valves is not liable to be disturbed either accidentally or by tampering.

Qbviously my shut-ori valves Inay be applied to other types oi faucets or valves, and the construction and arrangement o the parts niay be changed or varied Within the scope deiined by the appended claiins Without departing Yfrom my invention.

Having thus described my invention, what .l claiin, is-

l. in a faucet, a body having hollow opposed hot and cold Water supply arins, a mixing` valve in the body, said arms having gloubular outer ends foi-ined with inivardly projecting' thickened sockets Which latter are interiorly threaded, valve rods in the arins to control the entry of Water into the body and having exteriorly threaded outer bushings having interior threads en- L with the valve rod threads and having exterior threads engaged with the socket threads so as te constitute supports tor the rods, the innerl ends of the bushings being` countei'bored, and packing in the counterbored perts of the bushings the outer ends ot' the valve rods having screw-driver receivslots.

ln a telnet, a body having hollow opi hot and cold Water-supply arins, a i valve in the body, said arins havinger outer ends torined with interiorly thr ed and inwardly projecting sockets ha ving perforated bott-oms, valve rods in the arrrn extending through the perforations of the bottonis et the sockets to control the enwaiter into the body and having extcriorlv threaded outer ends, bushings in the soelre l vving' interior threads engaged with the valve rod threads so as to constitute supports tor the rods, and having` exterior threads engaged with the socket threads, packing between the socket bottoms and the inner ends oi the bushings, and nieans to e'ect rotation ot' the valve rods Within the bushings.
